PATENT OFFICE- HENRY V. P. DBAPER'AND NATHANIEL OOVINGTON, OF HANNIBAL,MO.

IMPROVEMENT IN APPARATUS FOR SUPPLYlllG LOCOMOTIVE-ENGINES WITH PUREWATER.

Specification forming part of Letters Patent No. 134,263, dated December24, 1872.

To all whom it may concern:

Be it known that we, HENRY V. I. DRAPER and NATHANIEL CovmerombothofHannibal, in the county of Marion and State of Missouri, have inventeda new and valuable Improvement in Condensers; and we do hereby declarethat the following is a full, clear, and exact description oftheconstruction and operation of the same, reference being had to theannexed drawing making a part of this specification, and to the lettersand figures of reference marked thereon.

Figure l of the drawing is a representation of a railway water-tank withcooling-reservoir attached, inclosing condenser. Fig. 2 is a sectionalview of cooling-reservoir and condenser,

with pipes, 820.

This invention has relation to railroad water-tanks and it consists inthe combination, with a tank, of a steam-boiler and a steamcondensingapparatus for thepurpose of providing a supply of perfectly-pure water,the product of condensed steam, for the use of locomotives.

Referring to the accompanying drawing, A represents a railwaywater-tank, upon the top of which is placed the cooling-reservoir B,supplied With cold Water, through a pipe, 0, by means of asteam-pump,'D. E designates a steam-boiler; F, a steam-pipe leading fromsaid boiler to a condenser, G, contained within the reservoir B, andcommunicating, by means of a pipe, H, with the tank A. The condenser ismade of metal, and fastened within the reservoir at a distance from thewalls thereof of, say, two feet at the sides, top, and bottom, enablingit to be completely surrounded by this quantity of water, which isconstantly passing in through the supply-pipe G and passing offthrouggrh the waste-pipe I, which leads from the bottom of the reservoirto the boiler or source of supply, thus keeping the condenser. alwayscool.

The steam, entering the condenser from the. pipe I*, comes in contactwith its smooth cold surface, and is immediately reconverted into waterfree from all impurities, such as carbonate of lime, silex, &c., thesame being precipitated. The steam being condensed, the water passesinto the tank A, and may be fed to locomotives in the usual way.

J designates the steam-exhaust pipe from the pump or engine, leadinginto the steampipe F, and thereby conducting the exhaust steam to thecondenser so as to prevent waste. K designates a stop-cock connectedwith the lower end of the steam-pipe F. This cock is closed until steamis generated. Afterward it is opened and the steam allowed to pass tothe condenser. 1

\Vhat we claim as our invention, and desire to secure by Letters Patent,is-

1. The stationary railway tank A, coolingreservoir B, condenser G,steam-boiler E, steam pump or engine D, water-supply pipe F, combinedand arranged substantially as and for the purpose set forth.

2. In combination with the subject-matter of the above clause, theexhaust-pipe J, when arranged as described, and for the purposespecified.

In testimony that we claim the above we have hereunto subscribed ournames in the presence'of two witnesses.
